Enti ecclesiastici. Perdita della qualifica di ente non commerciale e obbligo di contabilità separata
No full textLa Corte di Cassazione, con sentenza n. 526 del 14 gennaio 2021, approfondendo il concetto di prevalenza dell’attività commerciale svolta da un ente religioso e di contabilità separata, ha statuito che non spetta al giudice tributario concedere o revocare la qualifica di ente non commerciale, come conseguenza della prevalenza sui ricavi istituzionali, nonostante le previsioni dell’art. 149, comma 4, TUI
Experimental pull-out tests and design indications for strength anchors installed in masonry walls
No full textThis study deals with the identification of the mechanical behavior of chemical anchors embedded in masonry walls. 108 pull-out tests are carried out in five types of masonry walls built with clay brick or vertically perforated units with cement mortar. Different parameters are taken into account: embedment depths, masonry type, anchor position (injection either in brick units or in mortar joints). The axial load capacity and the failure mode are observed for each test. The results are examined by means of elastic and plastic models assessing the efficiency of anchors installed in headers, stretchers or mortar joints. The anchors injected in mortar joints are shown to have much greater pull-out capacity than that found for anchors in bricks. Passing from 90 to 160 mm of embedment depth, a minimum increase by 40% of pull-out strength is observed. The most common failure modes are the sliding failure, which occurs for short anchors or weak masonry, and mixed sliding/cone failure, for long anchors or strong masonry. An analytical model is proposed to design anchors in order to avoid or at least to limit brittle masonry failures and to identify the field of application of uniform stress models

Unveiling CO2 Dynamics in Perfluorinated Cerium-Based Metal–Organic Frameworks with UiO-66 and MIL-140 Topologies by Solid State NMR
No full textThe dynamics of CO2 was investigated in two ultramicroporous perfluorinated metal-organic frameworks (MOFs), F4_MIL-140A(Ce) and F4_UiO-66(Ce), that share the same linker (tetrafluoroterephthalate) and metal (Ce-IV) but have different topologies. F4_MIL-140A(Ce) displays an S-shaped CO2 adsorption isotherm associated with an adsorption mechanism including CO2 interaction with the Ce-IV open metal site and a structural rearrangement of the linkers. F4_UiO-66(Ce), belonging to one of the most investigated MOF families in the literature, shows a Langmuir-like CO2 adsorption isotherm hinting at no specific strong interactions with the framework. The structural factors influencing CO2 adsorption properties in these systems were found to affect CO2 dynamics, as revealed by line shape analysis of C-13 static solid state NMR spectra of C-13 isotopically enriched CO2 ((CO2)-C-13) adsorbed in the MOFs (1 atm) as well as by the analysis of C-13 longitudinal relaxation times (T-1), at different temperatures. The evolution of the spectral line shapes of (CO2)-C-13 in F4_MIL-140A(Ce) clearly indicated anisotropic dynamics of the gas molecules in the framework, which can be described as a localized wobbling motion on the adsorption site combined with translational hopping from one site to another in the MOF channels. This scenario was corroborated by C-13 T-1 analysis in terms of a relaxation mechanism governed by CO2 reorientations that modulate chemical shift anisotropy. Rates and activation energies were determined for the two motions. On the other hand, spectral line shape and C-13 T-1 analyses of (CO2)-C-13 in F4_UiO-66(Ce) indicated a fast isotropic reorientational motion, reflecting weak gas/framework interactions and high symmetry of the MOF cavities, and allowed the activation energy for the motion to be determine
A Self-Immolative Linker for the pH-Responsive Release of Amides
No full textThe administration of therapeutics using bioconjugation has been mainly limited to drugs containing amine, alcohol, or thiol functional groups. Here, we report a general procedure for the preparation of benzylic N-acyl carbamates suitable for masking the amide group in important drugs such as Linezolid, Enzalutamide, or Tasimelteon in good to acceptable yields. These N-acyl carbamates appear to be stable in plasma, while a qualitative analysis of further drug uncage demonstrates that, at pH values of 5.5, a classical 1,6-benzyl elimination mechanism takes place, releasing more than 80% of the drug in 24 h

Francesca Bertini
No full textFrancesca Bertini was an extremely careful guardian of her image and legacy throughout her whole life. A major star of the international silent screen, she has recounted her hugely successful career in different autobiographic writings and interventions. An invaluable source of information for the history of Italian cinema, these documents are notoriously reticent—and sometimes unreliable—about certain personal details of her life. For example, she never revealed to have been first registered in 1892 at an orphanage in Florence as Elena Taddei, the daughter of Adelina di Venanzio Fratiglioni, a single mother and possibly a stage actress (Jandelli 2006, 31-2). While many sources indicate her first surname to be Seracini, the only concrete information we have about her acquired identity is that she became Elena Vitiello in 1910, when her mother married Arturo Vitiello, a Neapolitan propman or furniture dealer. Bertini was introduced to the sprightly Neapolitan theatrical milieu at an early age. She got her first, supporting role on stage when she was just seventeen, in the widely acclaimed 1909 production of “Assunta Spina”—an intense southern melodrama by reputed author Salvatore Di Giacomo. One of the most representative texts of the new Neapolitan popular theater, “Assunta Spina” was later transposed on screen by Bertini in 1915. The final result is still regarded as one of the masterpieces of Italian silent cinema and an emblematic example of Verist cinema. By 1915, Bertini had already been cast in more than 50 films, including many one and two-reel historical reconstructions and a few features. The following years saw her continuing to grow in popularity, with her films gaining huge acclaim wherever they were presented, from Europe to Latin America and from Russia to the United States
